Zealand reared actress Anna Paquin and her British True Blood co-star Stephen Moyer have become parents to twins. The Hollywood couple, who married in August 2010, received an extra special anniversary present this year when the babies were born prematurely. ‘‘We can confirm that Anna Paquin and Stephen Moyer recently welcomed their twins into the world,’’ a representative for the pair tells People.com. ‘‘The babies were born a few weeks early, but are in good health and both Mum and Dad are overjoyed.’’ The sex and names of the babies have not yet been released. The kids are the couple’s first together, although British actor Moyer also has a 10-year-old daughter, Lilac, and 12-year-old son Billy from previous relationships. Moyer, 42, and Paquin, 29, began dating in 2007 after they met on the True Blood set. They got engaged in 2009 and married a year later in a romantic Malibu ceremony. The fifth season of True Blood recently aired in Australia on Showcase.
